how to combine the addon with ofxCrypto when loading file?

[moebiussurfing]

I would like to read an encrypted csv file using this addon:
https://github.com/jkosoy/ofxCrypto
My idea is to hide the file (previously encrypted outside OF) when using my app on an installation.
ofxCrypto encodes strings (md5 or sha1) and buffers using base64.

Now I am reading a plain csv file with ofxCsv and I would like to know how to start to try to do this:
I want to combine both plugins, and to modify ofxCsv to read the csv encrypted file, decode and read the rows/columns.
but I don't know how to manage ofBuffers and ofFile yet...
any help is appreciated.

i think this out of the range of this addon. the goal of ofxCsv was to create a simple csv parser for openFrameworks. for me it sounds like an other addmon. something like ofxCsvCrypto
